| 686574738 | A Horizon | a soil horizon; the layer below the O horizon. Formed of weathered rock, organic material, and often referred to as topsoil | |
| 686574739 | Aquifer | an underground layer of porous rock, sand, or other material that allows the movement of water between layers of nonporous rock or clay. | |
| 686574740 | Asthenosphere | Part of the mantle that lies just below lithosphere | |
| 686574741 | Barrier Island | a long, relatively narrow island running parallel to the mainland, built up by the action of waves and currents and serving to protect the coast from erosion by surf and tidal surges | |
| 686574742 | B Horizon | receives the minerals and organic materials that are leached out of the A Horizon | |
| 686574743 | C Horizon | made up of larger pieces of rock that have not undergone weathering | |
| 686574744 | Convection Currents | air currents caused by the vertical movement of air due to atmospheric heating and cooling. | |
| 686574745 | Coriolis Effect | The observed effect of the Coriolis force, especially the deflection of an object moving above the earth, rightward in the northern hemisphere and leftward in the southern hemisphere | |
| 686574746 | Drip Irrigation | method of supplying irrigation water through tubes that literally drip water onto the soil at the base of each plant | |
| 686574747 | El Nino | a climate variation that takes place in the tropical Pacific about every three to seven years, for a duration of about one year | |
| 686574748 | Hadley Cell | system of vertical and horizontal air circulation that creates major weather patterns, predominately in tropical and subtropical regions | |
| 686574749 | Headwaters | water from which a river springs; source | |
| 686574750 | Humus | dark, crumbly, nutrient-rich material that results from decomposition of organic material; also a product of composting organic waste | |
| 686574751 | Insolation | delivery rate of solar radiation per unit of horizontal surface | |
| 686574752 | La Nina | cooling of the ocean surface off the western coast of South America, occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns | |
| 686574753 | Lithosphere | outer part of the earth, consisting of the crust and upper mantle, approximately 100 km thick. | |
| 686574754 | Loamy | soil composed of a mixture of sand, clay, silt, and organic matter | |
| 686574755 | Monoculture | cultivation of a single crop on a farm or in a region or country; a single, homogeneous culture without diversity or dissension | |
| 686574756 | O Horizon | uppermost horizon of soil, primarily made up of organic material, organic waste, decomposing bodes and live organisms | |
| 686574757 | Prior Appropriation | water rights are given to those who have historically used the water in a certain area | |
| 686574758 | R Horizon | bedrock, lying below all other soil horizons | |
| 686574759 | Riparian Right | right, as to fishing or to the use of a riverbed, of one who owns riparian land | |
| 686574760 | Salinization | occurs when soil becomes waterlogged from excess irrigation and then dries out. As the water evaporates, the salt crystallizes and forms a layer on the soil surface. Prevents growth of plants | |
| 686574761 | Southern Oscillation | atmospheric pressure conditions corresponding to the periodic warming of El Nino and cooling of La Nina | |
| 686574762 | Thermocline | layer in a large body of water, such as a lake, that sharply separates regions differing in temperature, so that the temperature gradient across the layer is abrupt | |
| 686574763 | Upwelling | process in which cold, often nutrient-rich, waters from the ocean rise to the surface | |
| 686574764 | Watershed | region draining into a river system or other body of water | |
| 686574765 | Water-Scarce | renewable annual water supply of less than 1000 cubic meters per person | |
| 686574766 | Water-Stressed | renewable annual water supply of about 1000 to 2000 cubic meters per person |
